Product Details

The ADA4841-2 is a unity gain stable, low noise and distortion, rail-to-rail output amplifier that has a quiescent current of 1.5 mA maximum. Despite its low power consumption, this amplifier offers low wideband voltage noise performance of 2.1 nV/√Hz and 1.4 pA/√Hz current noise, along with excellent spurious-free dynamic range (SFDR) of -105 dBc at 100 kHz. To maintain a low noise environment at lower frequencies, the amplifier has low 1/f noise of 7 nV/√Hz and 13 pA/√Hz at 10 Hz.

The ADA4841-2 output can swing to less than 50 mV of either rail. The input common-mode voltage range extends down to the negative supply. The ADA4841-2 can drive up to 10 pF of capacitive load with minimal peaking.

The ADA4841-2 provides the performance required to efficiently support emerging 16-bit to 18-bit ADCs and are ideal for portable instrumentation, high channel count, industrial measurement, and medical applications. The ADA4841-2 is ideally suited to drive the AD7685/AD7686, 16-bit PulSAR ADCs.

The ADA4841-2 package features RoHS compliant lead finishes. The amplifier is rated to work over the industrial temperature range (−40°C to +125°C).

Evaluation Kits

Product Details

These evaluation boards are designed to help users evaluate the ADA4841-2. The evaluation board is a BARE BOARD. There are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.

The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials

So far most clamping amplifiers
have relied upon an output clamping architecture and
are called output clamp amps (OCAs). A new architecture
called an input clamp amp (ICA) offers superior
clamping accuracy and lower distortion.

Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
